    The 612 and 599 are built on nearly identical aluminum chassis, one with 2950 mm wheelbase and the other with a 2750 mm wheelbase. Drivetrains are completely different with the 612 carrying over the Type F133 engine and single plate clutch from the 575 and the 599 with a Type F140 engine evolved from the Enzo engine and a twin plate clutch. OTOs do use the 599 gearbox case and twin plate clutch plus Superfast I F1 software, still with a Type F133(H) engine.

    The information on the OTO is new to me. It seems like more people are tearing down the 612s for renovation than the 599s.

    Dan- How did the marks scribed on the back of the cams line up? Those were very accurate on my 575M, even if kind of a small circle.

    Very close almost dead on. Its hard to get a good view of it even with a mirror on the 612 because of how tight the head is against the firewall.

    I really struggle with this idea that the OEM timing marks can be at all out. In any kind of well made engine (let alone a Ferrari engine) there is just no reason why the timing marks should be off at all. I can get that in the tuning world, you might want to adjust the cam position, especially if you’ve got a non-standard cam, but in the OEM world, where you really only have one definition of what the correct position is, then the timing marks should be spot on. In fact, the easiest time to get the position marks right has got to be during manufacture, as that’s when all the dimensions have to be perfectly well defined. In situ, it’s got to be harder to get the position mark with the same accuracy.

    What am I missing here?

    That is because they are assembly marks, not timing marks. They are there to guarantee you will not bend a valve when you replace the camshafts and torque down the caps. The timing marks are scribed on the rear of the camshafts after the cams have been timed/degreed at the factory.

    Appreciate your replies gents, and I’m honestly open to what any expert has to say. That said, I still find it amazing that if there is an accurate timing mark, that they wouldn’t just put it on the front. They had been making this engine (in one form or another) for decades by the time the 612 came along, so such a glaring ergonomic flaw is hard for me to get my head round.

    Unless there’s a good reason that im not seeing?

    As above- great work being done. Thanks for sharing.

    Been that way forever, why change? You just have to understand how they do it, and now you know.

    When it comes to the engine work, what prompted it? Was the car abused/neglected and it was seen to be in need of attention or is it just proper maintenance with the age/mileage of the car?
